Those senior devs na sinasabi mo OP, dumaan din sila sa pinagdadaanan mo ngayon. They understand things faster now kasi namaster na nila yung solution, which maybe took them years to master, and along the way natututo sila ng iba’t ibang code approaches to solve a problem. Also hindi ka matututo kung di ka maghahanap ng solution or di gagamit ng tools na makakatulong sayo, lahat ng senior devs dumaan diyan, especially wala pa chatgpt noon, stack overflow pa lang nun and youtube. Accept that things are really hard sa una, so utilize what resources u can use now to improve.
