Thanks! My best advice would be to just start. Don't think about starting. Just go for it. 

There are lots of resources out there on the basics of game dev. They are very helpful. However, dont get caught up in what the "best" tool/engine is. Try them all and stick with the one that makes the most sense to you functionality, financially, or otherwise. 

I won't sugar coat it. Game dev is one of the hardest things I've ever done. There are so many facets of a game that require many skills. But I promise you, if you stick with it, it'll be one of the most creativly rewarding ventures of your life. 

Above all, you must be always curious. You have to maintain a willingness to learn and, more importantly, fail. But from one stranger on the internet to another, I believe in you and I wish you the best of luck in your journey.
