I think it's more important to realize that it doesn't matter how much time you spend studying everyday. Instead the main thing is to make sure you spend time frequently, no matter how small the interval.

Spending as little as 15 minutes everyday is going to prove way more effective than spending 2 hours each day for only a week and then nothing for a year.

What you will realize after some time is that the 15 minutes that you spend everyday helps you know the overview of what's going on, and once you start discussing such things, you feel good that you know something. And knowing that small something will motivate you to know more.

So my answer - it is not fixed. But I make sure I spend at least 15 minutes each day studying/reading on something new and relevant to my work.
