+1 on not trying to teach yourself. Many attempt this because the bass guitar looks easy. Plug it in and hit the strings and away you go, etc. Playing bass guitar is not a solo instrument, it is for playing in a band and doing by yourself esp. trying to teach yourself is a waste of time. ........
Everything in this paragraph is wrong.
1) Bass guitar is easy.
2) It is about just hitting the strings, it's knowing which ones to hit, when, and how hard is the key. If you aren't hitting the strings in some way, how are you playing? Upright with a bow?
3) Many career soloists out there will disagree and disprove that statement.
Bass guitar is like any other instrument. With time spent on proper practice anyone can do it, some will be better than others or progress more quickly, but you will get better.
The question you have to ask yourself is how serious are you about playing? Do you want to jam in your basement along to your favorite tunes (get some tab books) or do you want hook up with a band and play some shows at some local dives (get a few lessons to get you going)?
I am self taught, never had a lesson and I have been playing for 16yr, not constant, but more often than not. Longest stretch I went without playing regularly was during Marine boot training and combat school, so around 5 months. I know if I had taken lessons I would be a more knowledgeable player but having taught myself for so long mostly by ear I can improvise and create original parts to songs that sound good. I have a more loose style that people seem to like.
Some self taught players end up sounding sloppy and this is due to poor technique. This is mostly what you see on YouTube, guys/girls that pay more attention to getting the notes of a particular song exact rather than playing cleanly, clearly, and consistently. If you practice proper technique, you will never regret it. Poor technique is the most difficult thing to overcome. The best advice to break bad technique is to put the bass down and walk away for awhile to allow yourself to forget and who wants to do that?
Someone else mentioned getting a better bass than $175 can buy you. You can score a decent Ibanez for less than that and get a fresh set of strings and a full pro setup. The works, get the frets leveled, nut filed, bridge adjusted. You won't be sorry. There is nothing more frustrating than trying to learn on an instrument that won't stop buzzing no matter what you do. It's worth it, and even the cheapest Ibanez basses respond very well to a good setup. They are built well, just not fine tuned from the factory, you gotta do it or have it done. Again, totally worth the cost.
