i have decided to temporarily stop with the lessons from scrimba website to build projects on my own. and this has made me face a lot of obstacles on my journey

1. it's easier to see where it needs to improve as now i have to use my own problem solving skills to code an app
2. there's no one there to walk me through the solution to step to step and finish a puzzle. i had to look for solution from youtube, blogs which is nice but i ended up figured out my own solutions this decision has made me doubt a lot about myself which is normal (i want to believe so). am i able to pursue this? am i smart enough for this?what is wrong?
