Promises and letdowns

1) Is life one spiral from birth, where from early on, we and those around us set impossible targets for ourselves that we are rarely going to meet, thus there is inevitable but surely crippling letdown?

2) Must we in the bitter end accept the duller alternative in lieu of the more exciting, albeit ephemeral option in trade for security?

(How will we ever know if the aforementioned "exciting but ephemeral" option will ever befall us? Shall we just close our eyes, hope and believe? Is hope and believe all we will have to survive on? And what if the only two reliances we grasp onto in the end betrays us, and nothing "exciting" ever comes?)

Hypothetically, we swing from day to day "accepting the duller alternative". It's not unbearable, but it is somehow not quite as electrifying as we've come to imagine, even though we are not entirely sure what our imaginative alternative life would be anyway.

Should we have, since the start, lowered the standard bar so we never shall again set those sky-high aims to avoid the constant mediocrity? Haven't we, inadvertently, accepted the "duller alternative", in order to avoid disappointment?

(Moreover, does exhilarating and exciting always need to be accompanied by brevity? Are there any occurrences which are stimulating, yet still long-lasting? Few, very few I imagine...)

Suppose one day (whilst still holding out for something better to befall), we decided to get up and act instead of perpetually "hoping and believing" by relocating to a bustling metropolis, or heck, even to Peru to open a llama farm in the open country. But after a long period of settling in to the point where we could comfortably call the new destination "home", the sense of "excitement" begins to pale and mediocrity settles back in, and we realise that life now is not so different from back then. So is it true that we may as well not actively persue the "better", and has this proven that the "better" always has brevity trailing in its wake? Can it never be lasting?

After the initial rush passes, doesn't everything degrade to the "duller alternative"?

Does this mean that we are presented with no other choice but to always accept the "duller alternative"?
