I have been in similar situations. Keeping following things in mind usually help me: * At any time only one task should have the top priority. * Consume less, create more. * If possible, complete the task at hand. Context switching has its own overhead. * Do not have a lot of things lying around (includes browser tabs/windows). They contribute to cognitive load and may cause cognitive dissonance. * Your health and peace of mind are important than all other things. So, always find out time for sleep, diet and exercise.
