Which road should I take? :s

I've been living (can I say I've been passing for?? No.  Having and Experiencing are possibilities.  Living is ok, but it sounds kind of redundant because of your phrase in my life.) moments of indecision in my life. Despite the fact  (Even though) I'm not an adolescent anymore I have been facing some terrible situations. All of them are, in certain ways, linked to my professional future. I don't know which way to choose. I am just like the <strike>persona</strike> character of that poem by Robert Frost, "The road not taken", but <strike>to</strike> for me it's been worse because I'm just at the beginning of the whole situation. I know we always have to make choices or to <strike>take</strike> make decisions, but I am afraid of <strike>taking</strike> making the wrong one.
I think I can wait a little more time <strike>until to make</strike> before making my choice. I'll think and rethink my possibilities in order to <strike>make</strike> do the right thing. But I know sooner or later (mais cedo ou mais tarde? Isso mesmo!) I'll have to take some risks.

Good job!  Some advice:  Always take the high road.  ;)

In this context, it means "rather." Make that three people = Rather three people = Three people and not two people. The speaker is correcting his previous words. I hope this helps!

Generally, a university is larger than a college and offers advanced degrees (Masters, Doctorates, Professional degrees in medicine and law) in addition to undergraduate degrees (Bachelors). Also universities are generally divided into colleges. For example, a university might be comprised of the College of Arts and Sciences, the College of Engineering, the College of Architecture, the College of Law, the College of Medicine, the College of Business, etc. I hope this helps!

I've never heard it expressed this was exactly. In my experience, it has always been "Might makes right."

Contradictions

It's funny. Most people I know say “oh, I like sincere people! a true friend must be sincere! a true girl/boyfriend must be sincere! my neighbours must be sincere! sincere, sincere, sincere!”, but when you do it – I mean, when you are sincere with them –, they act like you were offensive, rude or even unfriendly. Some of them start being hostile with you because of that. Well, personally I prefer very much those who say directly to me what they think <strike>than</strike> to (over) those who smile falsely to (at) <strike>you</strike> me <em>(I would use 'me', because of its earlier usage in the sentence)</em>, and just after they turn around, start saying terrible things about <strike>you</strike> me. Anyhow, that's what they call <strike>by</strike> civilisation.

Very good!  Despite the British spelling.   ^_^

I have a definite opinion on this topic.  I personally like the half Windsor.
