You need to get out and talk to new people. This will energize you and inspire you into new things and thinking. I have been a stock trader for years and was so isolated for so many hours each day. It was so depressing and I avoided everything and everyone. Until I had to change and find some answers. I met new people everywhere and my life has never been the same since. I preach socializing in person to everyone and I was not social for years, it was tough for me. This brings lots of happiness and a lot of possibilities in life.
I often think of doing this, but I think its strange to just walk up to someone and start a conversation.
It's not, we just assume that in our mind. I thought the same until I did this always and proved myself wrong. When you believe people will embrace you and love you, they do. Own it when you approach people and act like you good friends. Guarantee you it will work on most people. When it doesn't just be fine with that, it's ok people are growing.
