I used to have a similar q&a when I taught Bass guitar to budding John Entwistles and Mark Kings, and my response was always the same: Be comfortable with the level you are at the moment, but always be looking for ways to move up to the next...
In other words, there is ALWAYS going to be someone who does it better, faster, bigger, is more accurate, prototypical etc. etc. but you mustn't think that because this is the case your efforts don't have credence; they do.
If you never achieve Magazine Cover status, or be heralded as the next Big Thing in your chosen area, it doesn't mean you are a failure or that what you have done is worthless or has no value. Everyone, without exception, started with the basics and their journey will be different to yours; don't try to be them 'cos there's no way you can travel the same path, and even if you did the result wouldn't be the same 'cos we're all individuals...
If people would stop treating every artistic effort with an X-Factor mentality there would be far fewer artists/modellers dropping out of creative arts due to lack of applause...
Encouraging those modellers who have just started out and don't know how to wire electrofrog points or scratchbuild a station platform is important to them as an individual and the hobby as a whole; thankfully there are plenty of people on this site who are much further along on their modelling journey who accept that modeller's attempts as valid and show them how to keep improving...
I don't believe there is an ultimate "IT" to be attained as that would mean the person arriving at "IT" would then have nothing to improve on and have achieved perfection, which I would humbly suggest is impossible, and if a group of people begin to dictate what "IT" should be they immediately send out the signal that all those who haven't reached "IT" are failing in some way thus creating a heirarchy among those the group consider to be close to "IT" and introducing an arbitrary system of grading people's efforts which will always be unfair...
Sorry; rant over, it's just that I've seen so many musicians sink into depression and give up because they didn't get to play Wembley and make the cover of Rolling Stone, and would hate anyone here to go down a parallel route in railway modelling...
