njjen3953, (..and everyone else) YES, try to fulfill your fantasies!
What's being said here, is, basically, don't try to fulfill your dreams or fantasies, because you may not make it, or, if you do succeed, it won't be as good as you expect, and you'll be disappointed.
If you don't try to achieve those fantasies, you'll become depressed and your goal in life will be to sit at home and hope something good comes on TV. My family never tried to do anything, go on vacation, nothing, because "Oh, something might happen. You might have a wreck, or be robbed. And besides, it won't be worth the money. Oh, you'll be disappointed, it won't be as fun as they say. Oh, that for OTHER people." And because of this, my dad died sitting at home, watching TV, and doing and going no where. He was never very happy because of this. My mom seeks to do the same. You never get extremely happy, or sad. You're just THERE, existing, waiting to die. What's the point of living, njjen3953?
Yeah, okay, you may try and fail, the other person may laugh at you. Well, hell's bells! They suck for laughing at you! Go on to someone else. (Unless the fantasy is with a specific person.) Okay, and then, one day, lo and behold, you are able to live your fantasy. It will either be less than, good as, or better than expected. I hate to tell you, but it will probably be....BETTER than expected. Because you will be doing it in REAL life, njjen3953, and not merely DREAMING about it. But you're also forgetting another important point - after it's over, oh God, you'll have those wonderful memories to remember for the rest of your life!
And then, obviously, you may create new fantasies you wish to fulfill, or you may be lucky enough to repeat your fantasy, in a different way. But to never even TRY, I just can't understand it. Yes, you are guaranteed with never trying that you will NEVER be disappointed. But then, life will never be fulfilling either. It will just be stagnant and mundane, and life will devolve into "I have to go to work today, so I can go home and fall asleep, so I will be able to get up and go back to work tomorrow...and on and on until I die."
I say, start as soon as you read this message in achieving your fantasy. And then tell everyone how it went after you have achieved it. I'll be waiting.....
...oh, and of course, good luck....but I WILL be waiting for your eventual success and state of perpetual or permanent bliss that will follow....
