You are finally reaching the classic, inevitable scenario (well the biggest one of them all):
Here lies the fork in the road. You only choose one path and you can only see as far as the horizon from your position. Once you choose one to walk down and explore beyond what you see, you cannot go back and walk down another path. So traveler, make your choice as to what to do, walk down this path or that path and ponder forever on what you could've discovered on the other paths. You of course can stay here at the fork in the road as long as you want, but nothing happens here.
There are paths with many footprints embedded in the ground that act as a guide to something that someone has already done. Others have none where you are free to write the first encounter however you want it to be. The thing to remember here is that there are no requirements at this stage in file to travel down the hardest, most difficult path or a path that has never been traveled before.
The other important thing is that none can make the right choice every time. No matter how excellent a person may be, he cannot win every time. If he were to fight 100 times and win them all, he would not be human but a god.
You still have time...use it wisely.
BTW I plan to be a Software Engineer.
