I frequently remind myself that there is a time and season for everything. I'm not referring to noon in the winter but rather that you can't do everything everyday and therefore different things take priority at different moments in our lives.
For example, Danny and I used to play tennis multiple times a week in lower Manhattan. We had some great laughs and good fun (usually not so great tennis). We only played a couple times last summer because we were both working and we spent the weekends doing other things. We both look back fondly on our tennis time and wish we played the same amount now but our lives are filled with other activities at the moment.
Mostly my 'time and season' self pep-talks revolve around a hobby or favorite past time that I feel like I'm missing out on. But I only have 24 hours in the day to fill and therefore it is impossible to do everything. If I just kept adding things to my days/weeks/months/years without taking anything away I wouldn't be able to enjoy the things I am currently focusing on.
The great thing about 'time and season' means that just because I'm not involved in something right now doesn't mean it won't become a focus again in my future.
