I consider myself very skillfull in versionning tools.
In almoust every project I've had, both in school and work, I' ve dealed with different tools to track file changes.

However, in my personal projects I haven't used any dev oriented versioning tool, except the ones existent in cloud/platform services like google drive, dropbox or others similar.
Looking back.,I wish I would do more github projects instead of random folders shattered in every service I know
