Word boffins, please come and help me with words for this charity slogan, I have exhausted the thesaurus!

[MadreInglese]

I need words (or phrases) that mean fulfilling/worthwhile/rewarding/satisfying beginning with the following letters:

T
N
S (already have 'satisfying' but need another)
I
M
A (already have 'amazing' but need 2 more)

I've used all brain cells and bashed the life out of the thesaurus. Any MN help would be much appreciated

Nurturing/Nourishing?

Hmmm not quite but thanks Iklboo

I should explain a bit more really, sorry! We are trying to recruit volunteers so I need words expressing how volunteering makes people feel and what it can add to your life.

transforming
inspirational

appreciated

Tremendous
Nobilising
Sublime
Inspirational
Multi-orgasmic..
Awe-inspiring.

sharing
making a difference

included
active
motivated

oooh fab, keep them coming...

Bit more info might help, it's going to be in phrases like this -

want to do something REWARDING?
want to do something SATISFYING?

etc

Magnanimous

Altruistic

Philanthropic

ops there wasn't a 'P'

Advantageous

Influential?

These are GREAT! Thanks very much

Any more welcome....

Tremendous
Meaningful

I will be v.upset if you don't use mult-orgasmic, btw.

Puppy I'd love to but I don't think the powers that be will approve

(and if it was multi-orgasmic we wouldn't struggle so much to recruit volunteers! )

Magnanimous, special, super, invigorating, intuitive...

Maybe the problem is your using a thesaurus, a dictionary might be better

sorry should be "you're" ....Goodness I HATE that...
