2026 won't save you.
A new calendar doesn't fix:
- bad distribution habits
- avoiding visibility
- building in silence
- waiting for perfect

Everyone's saying business is dead until January.
That's exactly why December is the best time to build.
While your competition is:
- Taking breaks
- Waiting for the new year
- Saying they'll start fresh in January

Spent an hour throwing shurikens in Osaka.
Cost me 50 bucks.
Hit the target twice.
That's also how long it takes to write 5 LinkedIn comments that actually drive traffic to your profile.
Or you use engagefast.ai and do it in 10 minutes.
It's basically aim assist for your engagement.

I 3x'd my LinkedIn profile views in 3 weeks without posting more.
Here's what I changed:
Before: I'd spend 2 hours writing posts, pray for traction, refresh analytics like a psycho.
Result: 400 views, 12 likes, zero DMs.

97% of my EngageFast sales came from people who never liked, commented, or engaged with me once.
They just watched in silence.
You're optimizing for the wrong metric.
Engagement rate measures noise.
Lurkers measure intent.
The people paying attention aren't the ones commenting.
Cheers. ☕

I know it's hard to believe...
but yeah, Elon truly doesn't hate LinkedIn anymore.
And now he's running EngageFast.ai from the Cybertruck touchscreen.
He's at 24 comments in 13 minutes.

Engineers are trained to avoid errors.
Entrepreneurs are trained by them.
Your first landing page -> ugly as hell.
Your first cold DM -> cringe.
Your first pricing -> way too low.
Your first product -> built for nobody.

I had a Google Sheet with 50 names of people I wanted to engage with on LinkedIn.
Every day I got the same damn routine:
- open the sheet
- click profile 1
- wait for page to load
- check if there is a new post
- find something to say
- repeat 49 more times
Took me 90 MINUTES / day

Initially, I was a simple developer.
2 years ago I had (literally) ZERO clue how to:
- do marketing
- sell anything to anyone
- talk to users without feeling weird
- get anyone to care about what I built
A total black box.

I'm not special.
I'm not a 10x dev.
I'm not even that good at marketing.

First SaaS: NeoAssist. Failed.
Zero revenue, zero users who cared.
Family and friends kept asking how it's going.

- Zero fake vibes.
- Actually got more replies than before.

Just by using EngageFast.

Sounds small? do the math.
40 mins daily
= 5 hours a week.
= 20 hours a month.
= 243 hours a year.
That is 30 full 8-hour work days for one year.
