LOL, this is going to be pretty expensive to keep up with whoever you're supposed to keep up with.
Are you a natural athlete? Did you play sports growing up? Baseball? No, they're not the same, but it's a start.
Are you in good shape? Do you have a decent muscle structure in your shoulders, arms, hands, back, abs, hips, thighs and calves? Are you able to walk 3-5 miles across medium terrain in a timely manner?
I suggest you find someone that plays and ask them to take you to a driving range. Give them money for gas, pay for theirs and your range balls and buy lunch. You will get to hit enough balls that you will sleep well that night. You will be very sore the next day.
I'm not trying to discourage you, but it sounds like you're completely green about it. Golf is very technical, physical and mental.
BTW, I started playing at about age 11, we lived near a golf course, some of my friends and I would sneak on at dusk or such and play a few holes. We played through high school and I played some after. When I was about 25, I played about 2-3 days a week during the summer until I started building my first house. Golf clubs got hidden behind a bunch of stuff in a closet, I suddenly had a lot of projects to finish for years.
Every now and then today, I will take a few old balls out, break out a few clubs and hit across the front yard or take a few out to the edge of the road and drive some across the 13 acre field. I'm worn out then!
