So what are you going to go do? Find a nice cubicle job somewhere?
If you are truly a successful trader, then money should not be an issue - it's change that you are seeking. The "grass is greener" issue maybe?
Many good suggestions here already. The first thing you should do is take a break. There's a reason just about every employer out there gives vacation time, THE HUMAN BEING NEEDS A BREAK FROM ROUTINE TO ENERGIZE.
After a nice vacation totally away from the stimulus of the markets (and I mean totally away, no market news, CNBC/Bloomberg, Wall Street Journal, etc...) you should dedicate some time to learning something new. You need a challenge.
Try learning about a different twist on trading. Try learning options if you trade futures for example. At your base stick with what's making you steady income, but branch out a little. Maybe you might think about pursuing a small business interest in something that you like? Even taking up a new hobbies can change perspective.
The main thing is breaking the grind/rut. Hate to tell you this, but it's going to happen no matter what you do. It usually happens to those that become at least moderately successful in what they do. It's actually a good sign because it shows that you are making it, but it can lead to more significant issues if not identified and dealt with.
There are some that can become totally contented with the security of a rut, but there are those that become disgusted with complacency and start to actually get depressed.
I understand what you are talking about because I felt the same way with what I was doing before I started trading. For me, trading was my change. In the end, it's not about the money. Money is only a means of monitoring success/failure, a score of sorts. Money will always be around and you know how to tap into making more. It's a renewable resource as long as you have the desire to work for it. It's what you do with your resources and time that makes the difference in life. This is a key principle that drives many of most successful. People like Warren Buffet talk about this at length.
The unexamined life is not worth living. Take some time off. Reflect, reinvigorate and redirect.
Good Luck!
