Here is my way. I mostly pushed away and pulled out of relationships with people who seem to stand against my beliefs. Instead of convincing them I just moved on. I found that a lot of those who do not believe in my choice of investment and think I will fail are the same people who never listen. Know it alls who rather put you down and disregard your feelings with no logical reasoning. Sometimes it feels like they envy you or some thing.
I believe this is a healthy way of handling your environment. Keep negativity outside your bubble. Only keep close to you people who give you the ambition and optimism to continue. Not sure how many of you believe in this. But manifesting negativity has always brought negative outcome in my life. Surrounding myself by positive thoughts and positive people has brought a strong source of light all the time.
People like them are not really healthy to be with. Even if you explain your investment to them, they will always have a lot of negative to say. That's why it's better to get rid of them before I lost my focus to my own bitcoin investment.
