Instead of learning how to mix, just record your tracks to cassette and then back to your computer and all of your errors will be magically turned into "lo-fi".
Don't waste valuable composing time pressing buttons and turning knobs. It's a little known secret, but manufacturers of physical and VST synths actually save some of their own sounds onto the synths as a sort of Easter Egg called pre-sex. These sounds are always interesting and will save you a lot of time trying to make your own. Do a Google search for how to find yours.
In this modern day, capitalist world, money is everything. Remember this every step of the way. Do not use free software. There are super-expensive DAWs out there that will make your music sound better than it does in Reaper. Avoid Audacity at all costs for the same reason. If it's cheap, your music will sound cheap. Once you've bought a range of expensive hardware and software, you can pay back the loan by selling your music for a high price. Remember, if it's expensive, it's good. Get your music onto Beatport and iTunes and make sure it's more expensive than the other albums on there.
