Cant you become an engineer and do art stuff in your spare time, for the love and enjoyment of art? Isn't becoming an engineer a passion in itself?
I don't know. I think I'm just ranting because I'm very afraid I'll always be mediocre. I do enjoy drawing, but for this the destination is more important than the journey. If I'm never good, my effort will have been wasted. I'm even more afraid that, by the time I'm good, the passion will be gone. 10,000 hours is a lot of time to give to something and still have love for it. There are so many competent artists online that put up just a dozen or so pieces before disappearing. Why weren't they more prolific? Did they put in the time just for the sake of getting there only to realize that they stopped caring long ago?
I'll keep practicing, when I can.
Dedication, discipline, and commitment are one of the most difficult aspects of doing anything yourself, whether it be starting and running your own business, sticking with a passion, teaching yourself a subject otherwise taught through a class (one of the hardest things to do, at least for me). A lot of people just aren't driven enough to stay persistent.
Thinking too far ahead is never good. Considering the hours you feel like you need to put in, imagining that such a long time frame will suck the passion out of you, and wondering why others stop so quickly... All of that sort of speculation is meaningless and only serves to manifest doubt, cutting yourself short before you even had a chance.
I know, it's tough. I find myself trapped in those mindsets too at times.
In the end, you just have to do it for yourself! I think a lot of the reason people stop uploading publicly is because they aren't getting attention and are becoming demotivated, perhaps feeling like they aren't improving. Ignore that aspect and just keep going, doing your best to learn new things, stick to what you are doing, and you will improve naturally. People tend to notice someone who's really driven and passionate too!
It's a super healthy mindset to be in, being invigorated and passionate, especially if it's coming from you alone out of creativity. So don't think about losing it! Just think about kindling it.
