10 Steps to Happy Relationships

Be self-aware
Know what positives and negatives you bring into the relationship with you. Focus on the positives, but don't ignore the negatives, acknowledge them without accepting them. Understand that what you may see as a positive, others might not and what you see as a negative other's might see as a positive.
Be compassionate
Just like the positives and negatives that you bring, your partners do too. Try to meet others where they are and focus on their positives, and then give them space to sort out and own their own negatives. No one is perfect, we aren't always happy or strong or motivated. Be ready to accept those things and then help where you are asked in to help. Attempting to help when you are not asked, or trying to fix someone isn't compassionate.
Be yourself
Bring your best you and if you can't do that, at least bring the real you. Conformity helps grind off some rough edges when necessary but you shouldn't conform just to conform. People like authenticity more than conformity. Be you and be proud of you.
Define yourself, yourself
You are who you choose to be. Your past is an influence, your relationships are an influence, but they are unchangeable and do not define you. Let it be you who decides who you are and what trajectory you take versus doubts of the past or fear of losing a relationship. You will have to live with you for the rest of your life.
Be honest
Say no when you mean no. Say yes when you mean yes. Define your boundaries. Avoid unecessary secrets. Be honest about your feelings, but don't use honesty or the truth as a weapon. Always remember compassion, because compassion is a balance of honesty and necessity.
Give out of love
The best kind of giving is that giving we do without want or expecation of reward, it is also typically the kind of giving that is the most rewarding. Irony or coincidence? Regardless, focus on giving and other's happiness versus obligation and reward.
Be ready, receptive, and responsive
Things change, hard times hit, problems happen. It's good to focus on the positive, but the world is imperfect and everything is impermanent. Be an all-weather type of friend and when things change be there ready to listen, open to opportunity, and eager to take action when needed. This holds true for yourself as well - remember to be receptive to your own needs and your own hard times and be active in fulfilling those needs.
Listen
Listen first, listen second, and listen third. Hold your judgement and interpretation until things are done being said. Give someone your time and exercise patience. Repeat things back to the person so they know you know what they said. Be slow to jump to conclusions or solutions. Clarify if they need help before offering it.
Compromise
Compromise frequently on tasks and direction but not your values. Relationships are give and take, not necessarily equal in the moment, but equal over time. Learn how to compromise versus always trying to win or be right. Decide whether the relationship is what's of value or being right. There are times when being right is important, especially when it comes to core values and when maintaining the integrity of who you are. So strike a balance of being honest about yourself and your values and what you are willing to compromise on.
Practice forgiveness
This is always the hardest step to take in a relationship. . We get better at it with time and with practice, but it does take practice. It also requires mastering many of the previous items in the list. Yet, it is needed early and often in a relationship, before we may have had time to master those things. We must remember that forgiveness is not a one time act, it is a regular act of compassion, responsiveness, listening, giving, compromise and self-awareness.
