For five consecutive workdays, track every activity in 30-minute blocks. Not from memory at the end of the day. In real time. Use a simple spreadsheet or a notebook. The simpler the tracking method, the more likely you'll do it for five days.
For each block, record two things: what you did and which category it falls into. The categories for founder-led service businesses: Revenue generation (sales conversations, outreach, proposals). Delivery (client work, project execution). Operations (team management, process issues, internal meetings). Admin (email, scheduling, bookkeeping). Strategy (planning, positioning, offer development). Reactive (unplanned interruptions, ad hoc requests, fires).
Don't judge yourself during the audit. The goal isn't behavior change during the five days. It's accurate data. If you spend Tuesday afternoon answering Slack messages, write that down. You'll fix it next week. This week, just measure.
