I think the most difficult task to handle is when you gets everything like power,fame, money, very easily; and later you gets failed in handling this success.
Most common examples are many celebrities and powerful personalities. They have everything, but at one point of time, they feels this name and fame as burden over their personal life. Then they gets involved in bad acts like drugs, alcohols, etc. I don’t say they are wrong. But the fact is they need a support system to live, just like a common person live.
Many of us also want to be famous. But i think it’s not so easy. You have to sacrifice many things. One most common is your freedom to live and speak anything.
