Nice topic. I have thought about it several times.

I think it is a question of personal choice whether I grant myself free will. Regardless of whether some consider this to be proven or unproven, or they say this question cannot be answered. Nevertheless, we have an attitude towards it, insofar as it comes up as an issue. For me personally, the preferable construct is to assume my free will, because it seems more than nonsensical to me to assume the opposite. If I were to assume that I had no free will at all, why would I want to make any decision at all or take it seriously? I could just as well flip a coin and act according to what the coin tells me. Incidentally, deciding to do something is not a bad idea for self-examination. Because where the statement is "yes" for "heads" and "no" for "tails", I immediately recognise an inner resistance, depending on the result. Of course, I can also toss the coin more often and have a resistance with both results, in which case it just means that I think coin tossing is a stupid decision-making aid :)

The recognition of an inner resistance is probably what causes me to recognise my free will, because where there is a resistance, I seem to be struggling with something. Of course, this quarrelling first takes place only with myself and in my head, and then I could still ask whether I have free will towards myself, which quasi lets the self quarrel with the me. HaHa!

Of course, each of us knows at the same time that not everything is subject to our free will and that there are currents beyond our influence. Therefore, it is far too simple a question anyway and basically only worth pursuing if I am interested in a profound maturing process.
