Retirement and fishing is a dangerous combination. I'm not retired, but I've got extended time off from work. As a result I've spent near every day on the river. What I've noticed is that fishing is starting to seem like work and that scares me. Make sure you've got lots of hobbies, aside from fishing, like maybe tying flys or building rods or whatever.

My point is, and I never thought I'd say this, but fishing CAN get boring and if you do enough of it the excitement-factor can slowly fade. One of the things that makes fishing special, in my mind, is that it gives you something to look forward to during the dreaded work week. It helps to keep one motivated in life. But what I'm discovering, is that I need to get back to work before fishing becomes just a routine and isn't "special" anymore. Also, try different methods. For instance if you're a single-handed fly-guy, build a spey rod and master that technique. It serves two purposes. One, it gives you something "else" to do and two, it can help you become a more productive steelheader.

Good luck and enjoy your retirement. I've only got 30 more years.
