I think it is these things that you look forward to, your rewards (however you define rewards)which makes life meaningful. It gives us a purpose, a sense of direction, a reason to exist. You eagerly wait. Since you know there is, for certainty, a reward at the end of your daily 'struggle', the struggle becomes lighter to bear.
I also think it is important to reward yourself for a job you have done well, and to create anticipation for yourself.
If I am in a philosophical mood, it is because I'm reading a dense non-fiction book. I find the author tiresome but there are a few takeaways. The one thing I cannot stand is pretentious writing, and the other is pontification. This book has both. I now wish I had chosen another book to read as my first book of 2020. But now that I am halfway through it, I shall struggle and finish it :)
If you liked this post, I'd highly recommend the book Man's search for meaning by Viktor Frankl.
