If you keep going forwards with something you are trying your best with and trying your hardest to improve then , there’s no stopping you. It’s just if you choose to go the distance or just give up and stop trying new things. If you just give up trying then there’s no point at all because your not going to get anywhere by standing still. If you just go for it and with the new thing you have tried then yes there is a chance you will succeed , obviously it’s not a guarantee but neither is it impossible. My advice is to put everyone’s negative thoughts and actions towards your idea’s behind you. Yes listening to advice will be a smart thing to do if your mind has hit a blank but that’s obvious.
