If the past is quite successful, we tend to give overweight on the experience and rely on the same strategy and tactics to drive the business
If the past is quite a failure, we tend to give overweight on the experience and give up trying new ideas.
However, future is not same as past as most of the parameters are changed like assumptions, environment, people, timing and of course you also evolved. What worked out past earlier may not be necessarily relevant now.
For example, what strategies you used to build an organization of size 10 crores may not be workable for building an organization of size 20 crores.Mainly the business environment, customers, people are changed.
Likewise, what worked out for you at a managerial position may not workable when you are at a senior leadership level.
Similarly, what not worked out earlier, may work now for the same reason.
The point is that experience or legacy alone will not drive your future.Too much dependence on the past or legacy may not work forever.You need to continually drive new initiatives or effort to be successful in personal and professional life as everything is changing!
