Or, you could try being less like the least interesting man in the world.
But, for those of us who don't approach either extreme, it might be wise to heed Russell Davies' advice (via Kottke):
The way to be interesting is to be interested. You've got to find what's
interesting in everything, you've got to be good at noticing things, you've got
to be good at listening. If you find people (and things) interesting, they'll
find you interesting.
