No luck or no Skills

Hey all,
I just have a little Question how you feel about the "Luckfaktor" in
Poker.
I played a lot of Tournaments the last months and lost about 70$ in MTT
like
18000$ garantie 2,20$ buyin, DailyDollar etc. and some 45 Player Sitngos
for 1,10$.
Ther are too ways i play very tight, build a stack and to the end the
Chips run out.
Or i get out in the early Hands with a Badbeat.( KK in BB, allin Q 10,
call, Flop 10 10 Q and bye).
What should i play for Hands at the end of a Tournament when the Blind
are eating me?
I fold a lot hands like AJ or A10 suited against a big race, and when i
got AK i run against
99 or 88 etc and no A or K came when i got a Pocketpair A or K came and
push me out.
I think i need a Break to clean my Head from the Cards and Badbeats.
Somebody got some Tips for me to win a Big Tournament?
Yesterday i was placed 516 off 6134 Players in DailyDollar and got 4,50$
for that.
Sick, i was top 100 to the last 1000 then i got Cards like 6 3 off or 2 5
what would you win with that Hands?

Poker is a combination of luck and skill.
