Why to Validate Your Idea First?
Validation of an idea is to ensure that your idea actually solves a problem/pain, and has real demand.
The rudimentary risk at this stage is developing an MVP/full-blown product that users never really wanted in the first place.

How to Validate Your Idea?
Quick tips by Lenny's Newsletter:
Build a prototype, and test your early ideas on the real customers.
Listen to their responses, and anything short of “I want this!” is a “No thanks.”
Don’t build a full-blown product until you’re feeling real demand from the market.
Figure out, which market segment can you sell to most easily, and start from there.
Then develop a product that unlocks revenue for your customers.
