I am 41 years old. I failed at almost everything till 35 in my career. I was down at my last $800 in my bank account with a dependent wife and a kid. Somehow I found a good job at 35 and I became financially stable. This stability gave me freedom to pursue few other projects and I got success in all other things. So success will definitely come to you over time if you stick and plan for it. The biggest skills you need to develop are resilience and not taking yourself too seriously. We are a very small blip in this massive Universe and our goal is just to try our best and leave the results to almighty.
