My advice to people in this situation varies tremendously given their background and what they're trying to learn, but it tends towards the same general method: start with something ultra simple and achievable, repeat it a bunch of times (perhaps with some minor variations) until you're relatively comfortable doing it on your own, then begin to branch out. If you're stuck for ideas, show it to somebody else and see what they think; having a training partner or mentor can help you feel less overwhelmed.
My experience is that our needs and wants change over time, and they are shaped by our actions. Overcommiting to a future that we think we want can end up quite badly in my experience.
One thing to consider is how easy is to make minor mistakes that technically count as an infraction. When acting in good faith, the administration can acknowledge this and promptly fix it, as it happened to me during my immigration process.
Then there are random mistakes out of your control. For example, when I first moved to the US and tried to get insurance for my car, I received extremely high quotes from the insurer. When I inquired why, they replied that my file showed several traffic infractions years ago in a different state. Simply clarifying that they'd mistaken me for another person was enough to fix it. Imagine if instead they deported me to a prison in El Salvador without a chance to defend myself.
And this is not talking shadier practices, such as changing the rules so that certain things suddenly become offenses, or simply fabricating evidence against someone.
