Fishing is just like anything else you can use the time and get tired of it, I retired in 2004 and bass fished 5 to 6 days a week for 8 months. I learned more about fishing in that 8 months than I learned in the 40 years before it. I then went back to work for 6 years and started crappie fishing again after many years and have only fished 2 or three days a week for the last few years and still have a long learning curve for crappie but that is the fun of it.
Hope you enjoy it you have earned it!
