Do what you want because you can and because you don't want to regret tomorrow that you didn't. If you think you are capable of doing something you really want to do, you CAN do it and it's important to care less about what others think about that. Others can either motivate you or show you down - it's on you what you choose. More importantly, if you don't take that one step forward despite knowing your capabilities, you'll have to live with the fact all your life that - you didn't even "try".
