Really glad I could make some positive impact on somebody :) Yes, but it's really about knowing deep down that you are 100% in this (whatever that is for you) and not give yourself a choice. If you give yourself a way out, you will fail, because it will always get hard at some point, at that time, you just have to keep looking at how you can do it and forget about where it wasn't working, just keep pushing where it's working and keep at it. It will work out. I've already had success like this before, only I have chickened out of this mindset before, because I got scared and started to give myself a way out, that's where it started going down the hill. Just have a firm conviction that success is your only option. Easier said than done (like everything), but if you truly feel it, it's all you really need.
P.S.: I just remembered this book a friend told me about and it is a little bit what I am talking about, maybe you find it useful https://www.amazon.com/Be-Obsessed-Average-Grant-Cardone/dp/1469095181
