What is the lesson im trying to say, keep your focus even though things get tough, keep moving even though its slow, because eventually those sacrifices will have a positive results, never get tired,
because once you quit, you will never get those dreams came true
Actually not all have that perseverance. Elon is a great guy and we have seen it and his countless effort prevail. Im sure he have some failures too in his task or job. No one is perfect but if someone is quite afraid to make mistake then they never grow.
I myself tied with that and been contemplating eversince. Got some fear of losing and making mistakes. Until now its the same but its really hard to be that confident when you arent happy with what you do. Theres a difference. Someone is gonna pursue something he like obviously.
