Tohami, this is good advice. The only way to get somewhere is to actually move. A line is formed through two points: where you are and where you're going. The most important thing is moving from that first point to the second.
Something that I thought I should add is the concept of short-run versus long-run. In the short-run, there are fixed costs and variable costs. In the long run, everything becomes a variable costs.
This concept applies to your advice in that you are looking from the short-run perspective. There are some things that you can change and some that you can't. Do your best to work with what you have and start making a better life right now.
Although it is important to first begin changes from the short-run perspective, we must not forget the long-run. In the long run, everything becomes variable. There is nothing that you cannot achieve or change.
Start with the short-run, but always keep the long-run goals in mind. The only way to get started is by focusing on what you can do. The only way to maintain a steady course is to focus on a reference point far away.
