That horoscope stuff is sh*t, don't ever follow it. That "don't eat eggs today" stuff doesn't work. If you wanted to know anything about your present situation, you'd look at the "synystry" (cross reference) between your natal (stars at birth from birth location) chart and the stars in the sky at your current location that day. This can also work for, say, six months in the future. The aspects would determine general trends and how things could unfold.

That "I'm a pisces/libra/sagittarius" stuff is somewhat accurate, but not a full picture at all. You really have to look at your whole chart. On the basic level you look at your planets, what houses they are in, what constellation (and corresponding planet) rules the house it is in, and how the planets form angles to each other. I don't even find horoscopes fun, it's just kinda dumb. I'd rather learn the basics of reading charts and then do that, more consistent, accurate, and fun.

And to answer the question about destiny, yeah, of course you can. The stars show a general trend. Usually, the stars would indicate that you urge to take conscious control over your life (or some aspect of your life).

If you want to get into really deep and accurate stuff, learn about William Lily and Horary Astrology. Basically you ask a question and you look at the chart for an answer. It has, at various times for me:

Told me the direction of a lost item from where I asked the question.
Gave a likely hood for finding lost items, which turned out to be true.
Characteristics of where the lost item was and when it would be found.
Almost definite answers to yes/no questions
etc...
