Be Present, Carpe Diem, Existentialism?

All 3 different depths of living some of us swear by.
I know for sure, I have lived my 20 years by Carpe Diem”. I want to believe where I am today and the person I have become are all experiences from believing and living by the phrase. I was introduced to this at an early age, loving the movie, Dead Poets Society.
Now, living past quarter of my life, I have confronted my self and learnt that Carpe Diem has been good to me and now, to live life to its fullest, I can take it up a notch and “Be Present”. Just Sieze the Now WITH various conditions. Firstly, would be to inculcate the daily practices of Yamas and Niyamas.
 Be Present: Existing or happening now; current
Carpe Diem: Sieze the day. The phrase “And if not now, when?” (Pirkei Avoth 1:14)
Existential: maintained that the individual is solely responsible for giving his or her own life meaning and for living that life passionately and sincerely,[7][8] in spite of many existential obstacles and distractions including despair, angst, absurdity, alienation, and boredom.[9]  Simply, I have took these 3 ways of living as a comparison. As much as I would like to believe, I am not an existentialist. May I say, I care too much to be such as describe as someone who only has “I” in her dictionary.
Definitely, a careless and carefree person who seizes every moment and lives her life. That is me. The risks, physically and mentally are always seen as an excitement for me rather than a challenge. “What is there to lose?” One question I am always asking myself before delving into matters or choices I make in taking care of myself, enjoying the fruits of labour, getting into trouble for I believe “You only live once!” who cares what people think, just as long as I think I am doing something that will not hurt others, I am good to go. Will I make that extra effort, spend that extra hour to make it work the way I will be happy with? Yes, I definitely will. IF not, why do it? It is also an All or Nothing attitude.  This confidence did not just come by the snap of one’s fingers, it is the people around me that I have to Thank. They have built the confidence in me to be able to say. “Let’s just do it! I know I can more than just cope!” And if you really think about it, people like me who plunges into doings just by the ‘feel’ of it, often gets hurt. We get burnt playing with fire. There is always the Pain to know the Joy. Having said this, every ounce of the dead cells while getting burnt is worth it because I have learnt. What I am learning to do is to Get burnt once and move on and not get burnt once and continue with playing with that same matchstick. You burn and you end up in ashes, nothing is left for you to fuel up your energy. That would be the ultimate dumb.
You need that understanding and the right guidance to bring you out of the rut and make your ‘practice’ a perfect one. I have found my answer in the 8 limbs in my path to Be Present. I would like to believe if one has Self- Respect, a lot of the practice leading to Being Present will fall in place.
Now that I have the Carpe Diem Zest, I will take that and walk the path of a True Yogi.
