How do you say "yes" or "no" when you wanna be on both sides of life?

I have always been on the confused side of life, have always wanted a little bit of everything.whether it is being an astronaut or a painter or a musician. I want to be a part of everything.I Can never make a decision between 2 flavours of icecream or 2 of my favourite dresses. Most of the times i end taking both or none ( doesn seem fair to leave only one of my favourites behind you see! ).
When it is about material things, it really doesn matter if you choose one or the other. But what if a person who by default cannot make a decision, is forced to make life altering decisions? What if the decision affects the people you love. How do u pick one from the other when you love them all equally?would you listen to your heart or would u just decide logically?

family or love, career or love , family or career , life or death , good or bad, chocolate or coffee? ;)

Here is what I do, i think and think and think and at the end of each day end up at the start. trust me it never helps!

In all of this mess unfortunately the only one at loss from both sides is YOU and making a decision means that you can never have both, no matter how much you love each one of them.

Should we just be mere spectators and let the events unfold and resign ourselves to the future? Or should we have the courage to actually make these decisions and be ready to face the consequences of our actions? Or should we just aim for a middle path where no one is ecstatic but all of us are content? I wish there was a correct answer, but unfortunately i haven't found one.

I'll never know what its like to be in the shoes of someone who can make decisions on the fly and have the courage to face the future. And of course........ i envy all of you who can do that!
