How to inculcate study habits in my 2 year old child?

2 yrs old, don't u feel your kid is too young? Why do u want to ruin his/her fun years? These beautiful years will never come back. Pls just let them have fun. Explore everything. Student years will be for the next 20 years. Then the grind of job and career and marriage etc. I just don't agree to this. Till your kid is at least 5, there should be no such pressure.
