Are you hesitating?
The biggest problem the man is suffering from is “hesitation.” Try not to overthink. Start implementing your solution immediately, and work on developing it consecutively. Do not think that you can plan an integrated project on paper.
Perfection comes with work, starts simple and transparently, and the complexities will impose themselves later. It is essential for your implementation of the solution at the beginning to be simple, uncomplicated and directly targets a target segment that enables you to observe and follow them directly.
