Whatever you want
1. Pick an unobtainable goal. I had a big goal that I achieved and the sense of diretionlessness was real. Some people say it's better to have a goal you can never finish like "meet as many artists as you can" or "end hunger" as it'll continue to be your guidepost in life.
2. Enjoy the process. If you're working just to get to your goal and you achieve it, you'll have a few moments of bliss when you do and then it will fade. If you enjoy the process itself rather than just the end result then you can experience bliss more often.
You could also start hiking taller and taller mountains. 14k or higher is where it starts getting fun. The mountains get as high as you want.
Learn how to ride a motorcycle. Super useful if you live in CA. A lot of people think its too dangerous, but honestly a little danger is good for the bones. We put ourselves in too many bubbles. The long-term goal could be to ride down Baja.
Have you tried to pick up cooking? Make advances recipes? You could have a goal of cooking for a huge party and everyone being amazed at the food.
You are probably fine already, but if you feel that you want more, I would suggest to get some inspiration from a new paradigm you never did before.
I've seen this lately, and while he did come up with rather random looking goals, it seems it doesn't matter what they are if you devote yourself fully to them.

I kinda like my work and my life, but I feel like I should have a big future goal.
