1) From my birth I want to rise
But I shall fall, its no surprise
Everybody wants their reputation score to improve, but downvotes, vote reversals, and other rep-decreasing events are inevitable.
I should display approval from afar
But pedantic snobs is what you are.
Rep only goes up if someone else expresses approval of your actions (upvoting a post, approving a suggested edit, etc.), but they won't do that if they're too nitpicky.
2) I could produce a rise in rank
But not if my cachet has sank
Higher reputations gives more site privileges
Uplift me please, by 288*
And my master will reach another state
The OP needs approximately 288 rep points (284, when I posted this answer) to break the 2k barrier and achieve new privileges.
What am I?
