Does anyone else have this problem?

[25801wv]

I start collecting something & once I complete it or am near completeting it I lose some interest and sell it and move onto another project.

For example these are some of the things I have collected in the past few years (and then sold to fund the next purchase):

High grade (9's & 10's) cards that reminded me of my childhood (late 1970's through 1990).

Complete sets of the 1970's (never finished, just moved on after I had a few)

1956 Topps Complete low grade set

All 4 1933 Goudey Babe Ruth's (probably my favorite cards I have ever owned)

3 T206 Ty Cobb's

Pre WWII Collection - Ruth's, Cobb's, Gehrig's, Hornsby, etc.

Post WWII HOF Rookie Card Collection (was almost complete with the exception of a few including 52 Topps Mantle/Mays) I had Aaron, Clemente, Maris, Mantle Bowman, Mays Bowman, Yaz, Rose, Ryan, Reggie, etc. This was fun to build. However, for some reason I decided to get rid of them and start over.

Most recently I have started two different collections, collecting Pre 1920 cards with the idea of getting as many different type examples as I could & collecting Babe Ruths. Of course I am no where near complete & am already losing interest.

I figure there are only 2 things that could help me:
#1 More money so I wouldn't have to sell my collection in order to purchase more or
#2 - Medicine

I am thinking about selling all & either collecting only Babe Ruths or going after the Monster in low grade without any errors or SP's. Any suggestions?
