How much time should you practice in golf?

QUESTION:
How many hours per day or per week should I be practicing to become better at golf. I just started taking lessons, so I’m learning about how to swing. What are some suggestions, and techniques about overcoming fatigue. Yesterday I was at the range around 3pm and it was so hot, that my swing was off and I couldn’t practice effectively. I want to learn to become better at the sport..not necessarily to play for the PGA. Also, any suggestions about proper apparel to practicing at the range? I am practice at a public range, it is not a country club.
Also, why do my knuckles feel so sore, like arthritis?

Practice early in the morning while it is still cool outside. Practice every day and take lessons from a golf professional that you could find at your local golf club. The PGA.com website has instructional videos and they can also help locate a professional in your area.
