Everything will most definitely NOT fall into place. See my rant below for more on this.
Ignoring girls is also very, very bad advice as well. I did the same, and consequently never fully developed the skills necessary to properly "get a girl," as the expression goes. It has led to an amount of frustration that has nearly driven me insane, along with student loan debt.
I suggest a more balanced approach. Don't ignore girls, but don't focus exclusively on them, either. Simply being exposed to the ways of women while in high school will help you greatly later on in life.
100% true. I am a high school valedictorian who lived a sheltered life, and knew very little about what it takes to be a financial success in life upon entering college. I attended an excellent technology school (over, say, a mediocre tech. school, or a large major university) mostly because of the happenstance that it was nearby. I ran out of money (which is really more of a situation of running out of people who feel like cosigning for anouther $20,000), left college with an unfinished degree, and as a result of being in a program that I have since found to be useless unless you're taking it to the Ph.D. level (which I obviously can't do until I finish undergraduage work), have no real skills with which to help me pay off my $100,000 of debt. So, for the last 8 years I've been living with my parents, spending nearly all money earned from mindless jobs (that are really just for people who never went to college, as those are the only kind for which I'm actually qualified) on student loan payments, and not saving a single dime. My bank account literally has $63 and change in it right now. Seeing no way out of my situation, and having attempted to drown myself unsuccessfully, I HAVE BECOME INTENSELY BITTER. Perhaps as a result of the sheltered upbringing alluded to above (I live in a rural area, as that's where my parents live), I have NEVER been in contact with ANYONE who makes the kind of money that you claim. If you have any career-counseling advice, or even if you just need a place to dump some dollars on a charity case to decrease your taxable income, then I'm all ears & my pockets are open.
My advice to the OP: Don't *just* focus on doing well in school, focus on your studies, or any other vague mantra that gets floated. Don't "do what you love," either. Rather, create a list of in-demand careers. Then, from that list, choose the career that is least likely to make you want to kill yourself, and do whatever needs to be done in order to get the proper education, certifications, etc. Reject the choice if it includes more education (in either duration or cost) than you are willing or able to handle, and move on to #2 on your list. So, knowing all that, you should really maintain some focus on running, as it may help you pay for 'education' at a sufficiently prestigious university to guarantee employment after college. I only had hobby-jogger times, but by the end of your senior year you may have really good times.
