Keep at it.

I've only done two things right in my life: exercising and not drinking. I tried it at 17, didn't like the taste, didn't like how I felt, hated how my friends were behaving. Six months later I tried weed and loved it and decided one inebriant was enough; I hadn't had any alcohol since that first time and made it formal.

And a damned good thing. My tolerance was insanely high and if I had liked it I would have had to drink so much I would have died 20 years ago. In March I'll be 67 and I can bench press well over 200 pounds.
