What is fun?

I am feeling old. Not sure what is fun anymore. In my thirties; no children yet. What is fun?

Not going out; drinking, smoking and dancing. We like going to bed too early for that.

Is crochet fun? I love it but sometimes it is work too. I like tennis but sometimes I am embarrassed by my poor showing in it. Sometimes it is hard work losing all the time. Is it fun?

The pursuit of fun is much harder now. Friends are in other cities. Responsibilities to parents, career, partners feels more consuming then in the twenties.

Overseas in May was fun with my fella. Discovering Prague with him. What a wonderful city. Spending time with my family whilst we have new travel experiences. This was great. But we can't be travelling all the time, can we??

Looking back at photos. Planting native plants can be fulfilling. And watching them and other plants grow and flourish can be joyful. But is it fun?

The fella and I are on a roller coaster of emotions whilst we both have irregular casual work. Feeling terrible if we don't get to work. Is full time work the fun we are missing or is it the monotony of full time work that makes all the other experiences 'funner'?

Drop me a comment if you have experienced this feeling as well. I'd love some advice.
