Never being satisfied with our work is a common affliction that plagues all artists. If it's truly making you miserable and is something you can't live with, here are some steps you can take:
CRITIQUE: Post some of your music in the Members Compositions and ask for opinions and suggestions for improvement. We are usually too close to our own work to evaluate it objectively. External opinions can help point out the critical areas for improvement, as well as calling out things that are actually working well.
IDENTIFY ACTUAL PROBLEM AREAS: Creating music on our own, especially orchestral music, requires us to perform a variety of tasks that traditionally were handled by people who specialized in these tasks. It's helpful to identify which parts of the "production chain" are causing you the most dissatisfaction and address those areas. Roughly speaking, it can be broken down into composition, orchestration, and mixing.
- Composition: Are you unhappy with your musical ideas? Is it difficult to come up with melodies and motifs? Are you having trouble finishing pieces? Do you feel lost after you establish your initial ideas?
- Orchestration: Do your orchestral arrangements sound clunky, unimaginative, or fake? Do all your pieces have the same generic orchestral sound? Are your orchestrations not exciting and interesting enough?
- Mixing: Do your final recordings lack a professional sound? Do your mixes sound muddy and imbalanced?
EDUCATION: To remedy any of the above problem areas, consider enrolling in some online classes, or at least watch some good YouTube tutorials. Even just a little bit of knowledge can result in some noticeable improvement right away, but true meaningful change usually requires time and lots of practice, so just keep at it and don't give up, and keep soaking up more knowledge as you go.
TIME AND PERSPECTIVE: I usually hate everything I create, and sometimes I hate a piece so much, that I abandon it and move on. Then maybe a year later, I might stumble onto it and give it a listen, and much to my surprise, it's actually not that bad. Often when we're working on a piece, we have an idealized sound in our head that we're trying to achieve, but for whatever reason, it doesn't manifest, so we think the piece is a failure. But listening later, without any expectations, we're able to hear the piece for what it is and realize it's actually not that bad at all.
DON'T FORCE IT: Musical compositions tend to go where they want. If we try to impose our will and attempt to force the music in a particular direction, the results are often disappointing and we just end up frustrated. Relax and let the music lead the way. The results won't always be what you intended, but the process of composing will be more satisfying, and you'll end up with pieces that may be surprisingly pleasing.
Hope some of this is helpful.
