I find myself always running short on time during some tough decision.

1)my big hands are being reraised
2)A draw heavy flop came while I am holding a playable hand
3)when people raise me all in at the river with very little early betting.
4)when the possible scary card show up, i have to back track to all the prior betting arounds.

please tell me what is the first thing that you would call back or pay attention to when the above sitiuation happens?

for example should i think of the post flop betting first, the way the player have been betting or if i have the correct odd to continue?
So i can get my priority straight.

PS: i will only have 20 seconds party 25NL
