Here's a dream come true: Owning two of the best Nikon lens ever made: The 300mm F/2.8 AF-S VR and the 600mm f/4 VRII.
I came to the realization that one doesn't want to be old before 1) enjoying retirement 2) carrying a 600mm f/4 VRII.
Money is cheap, time is everything. Rich at 25 beats filthy rich at 50 –every–single–time. This is not some mainstream wisdom in the youth of today, unfortunately for them.
I could work until that I'm 35 and get richer, but here is a bet that I am not willing to make : That my health will be there in a decade from now. I can always go back to work. I cannot go back in time. Make the math. Make a plan. Make it happen.
