Try to let go of the past. Memories are only as good as the experience you have today. Draw conclusions from all the nice and negative situations and try not to lose them in the head again and again. Forgive those people who you once hurt, once again thank those with whom you were good. Mentally hug each of them and think that you can say thanks to them. After that you will feel at ease and a willingness to start with a clean slate.
You have to be clear about what you want to be in the future. To do this, you will require serious work, because you yourself have to decide what is "good" and what is "bad". This will inevitably lead to the collapse of stereotypes, which up to this time persistently imposed on society: "to get married once and for life", "a son to continue his father's work", "entering the University, you choose the profession of a lifetime", etc. you, as a diligent student, humbly followed them, not wanting to be misunderstood. But now you know exactly what you are in the right to build their lives.
Based on the previous step, formulate thoughts into specific goals, otherwise they will remain dreams. Do not be afraid, truly great people have changed their lives thanks to the most daring ideas. If your goals seem unrealistic, break them down into several stages, but don't lower the bar. Inspiration and new ideas will start coming to you with greater force as soon as the first result. Be confident in your abilities and do daily that will bring you to your destination.
The important thing is that you could use in building his new life – love and patience. Feel love for yourself and your business, appreciate loved ones. Don't give up if something goes wrong. No one knows how to live without losses, defeats and crises. It is possible to solve a particular problem, you just need to take a break or change tactics. But, if life doesn't give you critical situations as you learn the price of happiness?
