She has played it safe in her field so far and she has varied her roles without being a flash in a pan. Some heroines get typecasted into a certain role, but some of them play safe till they're strong enough to make risky moves. I am slightly hinting at Vidya Balan, she has carved her own niche that is too niche for her to be extremely popular. People like Balan for eccentric choice of roles, but people love Deepika, because she is building a base right now. Risky, weird roles will come. But that's for later. That's when she'll know that she can take liberties with her audience as well her choice of roles.
So, how can you apply the same thought to relationships? It's like this, you've got to "build" relationships. There is a lot that goes into building relationships. First you've got to know your materials, then you've got to know how to handle those materials, then you've to actually work those materials into something tangible and amazing.
Whether you're looking at romantic relationships or business relations, as long as these involve people, the relationships can be manipulated into any way possible. If you treat them right and do all the right things, when the time comes to do risky, maybe slightly wrong things, you can escape with less damage.
Those are all thoughts for now.
