Bankroll management control

Hi guys, Jazzmaker here

Just wondering what people do to stay disciplined and controlled with their bankroll. For me its very easy to control myself and play according my br size...IN the beginning. Later on after I build my br a bit and win some sngs and play some ring games I tend to start playing out of my br - in higher stakes sng, ring games, or mtt (which I never make the cash on for the higher end buy ins). I think Im too tempted by the higher stakes and high winnings

So any tips or just some good 'ol hounding to make me play according to my br? Thanks
