A man had better stick to known and proved pleasures, but, if he will venture in quest of new ones, he should not do so with a light heart.
One reason why we find it so hard to know our own likings is because we are so little accustomed to try

Context

“Indeed, if we could solve the difficulty of knowing what gives us pleasure, if we could find its springs, its inception and earliest modus operandi, we should have discovered the secret of life and development, for the same difficulty has attended the development of every sense from touch onwards, and no new sense was ever developed without pains. A man had better stick to known and proved pleasures, but, if he will venture in quest of new ones, he should not do so with a light heart. One reason why we find it so hard to know our own likings is because we are so little accustomed to try; we have our likings found for us in respect of by far the greater number of the matters that concern us; thus we have grown all our limbs on the strength of the likings of our ancestors and adopt these without question.” source
