How To Start A Start Up In 1st Year Of College ? I'm JEE Dropper Needs Some Guidance

Seriously asking guys , I don't know how to start it . I know there will be tons of problems coming on the way but I just want the guidance , how to start it how to approach it

I got 98.80 Percentile in JEE Mains 2026 so top NITs are secured I mean college also matters to start something big !

If it was tier 3 college the situation was even worse to start it .

I'm asking advice from the people who are way mature and experienced than me , I might sound childish but it's my actual doubt how to start it ?
