Here are some lessons I've learnt well. Some of these have come as benefits-on-the-side with my advancing years, others from the burnt-finger chronicles of my biography, and the rest from that holiest oracle of all, the last word in fountainheads, Bollywood.
1. Remember that there are always atleast three cameras on you, one of them capturing every detail in slo-mo. As true in the corporate world as on a cricket field and as in the final confrontation with Mogambo. You never know who's watching, and to what detail they're interested in your performance. When under pressure, he who resists the nose-picking shall move up. Helps to know where the cameras are though.
2. The movie isn't worth making if the hero hasn't struggled. If you're down but fighting the odds, you'll come back up. That's most of what Bollywood's about. If you're up, realise that there's a new trend of sequels. You going down real soon. There's a discussion in here, waiting to be trashed out, about what's up and what's down. Gives me another post.
3. Don't sweat the small stuff. Instead, invest time finding the right person that will. If I had to learn real estate to buy a condo, do my CA exam before filing my taxes, get a many-hued belt in an obscure martial art form before I could leap tall buildings in my next movie, I'd really never get anything done. Instead, I figure my time's better spent if I can locate portly doubles to do all of these things for me. Task delegation is key. My responsibility is finding the right person to delegate to. Of course, the accountability remains mine too.
